Rose plant named `Sweep Success`

ABSTRACT

A new hybrid tea rose plant is provided as developed from a seedling in a direct effort to breed a new variety. The new rose plant resulted from the crossing of parent varieties of Chablis and Pristine and features a vigorous growing habit, an ability to yield abundant blooms on an almost continuous basis, and distinctive coloration changing from beige at the base of petal to a light pink on both sides of the petal. High resistance to blackspot is also exhibited.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the hybrid tea class which was originated by crossing two knownvarieties, namely Chablis and Pristine. It is contemplated that thevariety will be marketed under the American Rose Society, (ARS)registered name of Sweet Success. Color descriptions are made inreference to The Royal Horticultural Society Colour Chart and the colorplates are indicated by number (e.g. 62D).

Artificial pollination was undertaken and the new rose plant wasdeveloped from a seedling with the primary objective of breeding a newvariety of rose plant with the ability to yield on an almost continuousbasis abundant blooms with a large number of petals. These objectiveswere substantially achieved along with other desirable improvements asevidenced in the detailed description below. The new hybrid tea roseplant of the present invention was bred in 1985, and the resultantseedling was propagated in the winter of 1986.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS AND DRAWINGS

The accompanying photographs show typical specimens of the vegetativegrowth and flowers of this new variety and its distinguishingcombination of characteristics, with the photographs being depicted incolor as nearly true as it is reasonably possible to make the same incolor illustrations of this character. The rose plants of the newvariety described herein were grown outdoors at Cincinnati, Ohio.

DETAILED DESCRIPTION

The following description is based on specimens of the new variety ofrose plant grown outdoors at Cincinnati, Ohio.

Type: Hardy; outdoor; bush; for exhibition, cut flowers and gardendecoration.

Class: Hybrid Tea.

Propagation: Maintains its distinguishing characteristics throughsuccessive propagations as budded plants, rooted cuttings, and grafting.

FLOWER:

Locality where grown: Cincinnati, Ohio.

Flowers borne: Singly, on long stems, occasionally with side buds.

Quantity of Bloom: Abundant outdoors, in Cincinnati, 4 to 5 cycles perseason.

Continuity: Almost continuous.

Fragrance: Slight, tea.

Bud:

Peduncle.--Medium long, green (143C), erect stiff, significant prickleswhich are randomly spaced. Illustrated in FIG. 6.

Before the calyx breaks.--Size-medium. Form ovoid.

As calyx breaks.--Light pink (62D) with a flush of dark pink (63D). Edgeof many of the petals have a red purple (61C) pigmentation. Illustratedin FIG. 1.

Bloom:

Size when fully open.--Medium --four to five and one half inches.

Petalage.--Very double; from fifty six to sixty four petals arrangedregularly.

Form.--Cupped, high centered; globular at first and becoming highcentered. Mature petals are highly recurved, as illustrated in FIG. 2.Center remains tight while outer petals become recurved and regularlyspaced. In the full open stage the bloom has evenly spaced petals withZinnia-like form, as illustrated in FIG. 3.

Petals: Leathery with a satiny shine inside and outside.

Shape.--Scalloped outer edge that is weather dependant. No apparentnotches and the petals are generaly oval, and recurved.

Color.--Yellow (13C) at the base changing to a coral (37C) on theinside, followed by light pink (62D) on both sides of the petal. Theedge often acquires a dark pink (63D) edge in temperatures greater thanninety degrees Fahrenheit. In cooler weather, with nights less thanforty five degrees Fahrenheit, the petals are almost completely whiteand retain only a hint of pink pigment, as illustrated in FIG. 5. Thecolor tends to lighten as the bloom becomes full, and colors aregenerally move vivid in fall season.

General color effect.--Light Pink Inflorescence with a dark pink edgewhen fresh.

Behavior.--Drop off cleanly; do not fade.

Flower longevity.--On the bush five to seven days in September. As a cutflower it remains fresh for at least three days at room temperature. Theabove color description is taken from fifty bushes grown in Cincinnati,Ohio.

REPRODUCTIVE ORGANS

Stamens: Many, arranged irregularly.

Filaments: Many, varied, red (45A).

Anthers: Small to medium size, yellow (19A).

Pollen: Yellow, moderate.

Pistils: Many.

Stigma: Straw Yellow (19B).

Ovaries: All enclosed in the calyx.

Hips: Pointed at the base, becoming ovoid; smooth sides, as illustratedin FIG. 6.

Sepals: Pointed, spear shaped and highly recurved.

Seeds: Large, number similar to Pristine in number.

PLANT

Foliage:

Leaves.--Compound of five leaflets; normal; large; very glossy; waxy.

Leaflets.--Ovoid with apex acute; base round; margin serrate (3).

Color.--Mature -- dark green (131A), often while maturing venation andserrated edges are dark red, as illustrated in FIG. 3. Underside istransparent red (60C) with green showing through.

Rachis.--Medium heavy; upper side smooth, underside thorny, asillustrated in FIG. 8.

Stipules.--Medium long; medium wide and reddish in color.

Disease.--Very resistant to blackspot and to lesser extent mildew.

Growth:

Habit.--Upright, moderately branched.

Growth.--Vigorous, tall to six feet in height.

Main stems.--Medium green. Thorns: Long, pointed slightly downward andgenerally bright red, as illustrated in FIG. 9. Prickles: GenerallyAbsent. (See FIG. 9). Hairs: None. Occasionally a unique thorn/pricklepattern appears in which the thorns are found in clusters while theprickles are on the opposite side of the stem, as illustrated in FIG.10. This thorn/prickle pattern may be completely unique.

We claim:
 1. A new and distinct variety of rose plant of the hybrid teaclass, characterized as to novelty by its vigorous growing habit, itsability to yield on an almost continuous basis abundant blooms, andquality and color of its bloom and foliage as shown and described.
